When I cloned base 7.0 for my JSONerrors branch a few days ago, I noticed the problem with .ci:
$ git status
...
#	modified:   .ci (new commits, modified content)
and also noticed that the referenced commit did not exist.

$ git submodule update
fatal: reference is not a tree: 8a2666a9deeb6c618bcc73ba80f1a83a878c7a84
Unable to checkout '8a2666a9deeb6c618bcc73ba80f1a83a878c7a84' in submodule path '.ci'

But it did not really hinder my work or stop me from cloning it. It just showed the error.

My git version is 1.8.3.1.
